So a few weeks ago I found out my GF of 4 months cheated on me with some guy she's been hanging out with. It hurt me a great deal. I've since forgiven her and she says she wants to work things out but I've realized I can't even trust what she says anymore. She blatantly lied to me this evening. We were talking on the phone and I heard a guys voice in the background, I asked who it was and she said it was one of her friends named Trevor. I asked to speak to him and she refused to put him on the phone and quickly got off. I called her back and asked her if it was Tarick would she tell me. She told me yes she would tell me that it wasn't him she promised it was her other friend. As I became nervous she became very angry with me and got off the phone again. I called back, and Tarick answered. I asked how come she lied to me and just didn't tell me the truth. I think that she is playing games with my emotions. I don't know how to take this. One minute she says she's in love with me, then the next he spending the night with her. I'm constantly catching her in lies. I'm thinking it's time for me to move on.
